Hi, I said I would reply re first tank of petrol. But I'm not sure I have a useful figure. When I bought the car it had 5 miles on the clock and supposedly a full tank. It said there was 465 miles of fuel. After I filled up it said there was 518 miles of fuel so I dont think the dealer/stealer supplied a full tank of fuel. The indicated mpg is 51.5, but they are usually optimistic. The calculated mpg is 45mpg but that would only be correct if the tank was full. I reckon I got about 50mpg, but I think this is low due to a number factors. 1. very frosty mornings and cold weather. 2. Unusual amount of short journeys in that period. 3. Only 1 longer trip 70miles).
Since then it has been indicating 60-64mpg. So I am expecting around 55mpg (compared to the 54mpg I used to get on the Prius - which is not bad, I think.)
I would love to know how it estimates miles to go. It started out as 5+465 =470 but by the time I filled up it was estimating 20 miles to go but the miles was only 318. (=338). Where did the other 132 miles go?. This reduction might have been partly due to the short frosty journeys.
Will check in again when next refill.
